Two ways to read the storm

How Donnelly saw the hail — from two instruments

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Where May 27, 2026 sits in Donnelly's hail record

This was Donnelly's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 2 storms we have logged here. Radar put the day's largest stone over Donnelly at 1" — the largest NEXRAD radar signature.

The May 27, 2026 convective day was bigger than Donnelly: the same system put hail over 172 other tracked cities, 6 of them in Idaho. Nearest: McCall (15 miles north, up to 1.25"); Cascade (21 miles south, up to 1.75"); New Meadows (30 miles northwest, up to 1.5").

These maps are stills from Donnelly's May 27, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

Ground reports

What people on the ground reported

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

The National Weather Service logged no spotter reports for this storm over Donnelly. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Shingle-bruising hail

What 1" hail means for Donnelly roofs

Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.

What this storm is worth to a roofer

$84K

Potential roof exposure — 7 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Donnelly

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar surfaces are detections and estimates, not confirmed damage. Last updated Aug 2, 2026.
